Abstract: Resonant valence band x-ray photoelectron spectra (ResPES) excited near the 2p 3/2 core level energies, 2p x-ray photoelectron spectra (XPS) and L 3,2 x-ray absorption spectra (XAS) of Ti and Mn in single crystals of 1T-Mn 0.2TiSe 2 were studied for the first time. The ioniccovalent character of the bonds formed by the Mn atoms with the neighboring Se atoms in the octahedral coordination is established. From the XPS and XAS measurements compared with the results of atomic multiplet calculations of Ti and Mn L 3,2 XAS, it is found that the Ti atoms are in the ionic state of 4+ and the Mn atoms are in the state of 2+. In ResPES of Mn 0.2TiSe 2 excited near the Ti 2p 3/2 and Mn 2p 3/2 absorption edges the Ti 3d and Mn 3d bands at binding energies just below the Fermi level are observed. According to theoretical calculations of E(k) the Ti 3d states are localized in the vicinity of the point and the Mn 3d states are localized along the direction KM in the Brillouin zone of the crystal. © 2012 IOP Publishing Ltd.
